Treatment Of Zygomatic Fractures

Non surgical Management

Reserved for

1. Minimal/Undisplaced fractures

2. Patients with medical contra-indications

3. The very elderly

 

Indications for surgery

1. Cosmetic deformity

2. Impaired mandibular movement

3. Diplopia

4. Infra orbital para/anaesthesia not certain that surgery improves recovery

 

Timing of surgery

As soon as possible elevation becomes difficult after 14 days. Long delays leads to fibrosis and resorption of fracture margins, increases difficulty and decreases stability

Delays sometimes necessary to allow dispersion of gross oedema and a proper ophthalmic examination usually includes a HESS chart

A zygomatic fracture will be firmly united in 3-4 weeks

 

Surgical Approaches to the Zygoma

1. Temporal fossa (Gillies) approach

2. Intra-oral

3. Percutaneous: stab incision/eyebrow incision / bicoronal flap

 

Stability of the fracture reduction depends on the muscle pull and attachments and the adequacy and accuracy of bony apposition at fracture sites

 

Fractures which may require fixation

1. Separation of F-Z suture and disruption of infraorbital margin

2. Comminuted fractures

3. Arch fracture

4. Delayed treatment

 

Methods of Stabalisation

1. Osteosynthesis by direct wiring or placement of plates

2. Antral support: pack/balloon or wedge

3. External/Internal pin fixation

 

Complications of Untreated or Poorly Treated fractures

1. Flat cheek

2. Altered papillary level

3. Diplopia

 

Complications

Retrobulbar Haemorrhage
